Research Projects

A Regional Comparison of Upwelling and Coastal Land Use Patterns on the Development of HAB Hotspots Along the California Coast: 2012-2017; to determine the key factors triggering toxic algal blooms off California, in order to provide early warnings of these blooms in two areas known to be bloom hot spots.

Forecasts and Projections of Environmental and Anthropogenic Impacts on Harmful Algal Blooms in Coastal Ecosystems: July 2010-June 2013; Primary objectives are to implement existing HAB models from Santa Barbara and Monterey Bay previously developed as research exercises, to test and expand these existing models in other regions, to begin developing a similar modeling effort for paralytic shellfish poisoning, and to provide consistent field monitoring and validation data to adequately assess the model results.

RAPDALERT - Rapid Analysis of Pseudo-nitzschia and Domoic Acid, Locating Events in Near Real Time: 2005-2011; to shift much of the burden of HAB monitoring to an automated system to ensure early warning of impending blooms while minimizing unnecessary and expensive field-based sampling and lab-based testing. Results will advance understanding and ability to predict HAB events.

California Program for Regional Enhanced Monitoring of Phyco-Toxins (Cal-PReEMPT): 2004-2009;to expand the current capabilities of the California Department of Health Services by incorporating new in-field monitoring technology, implementing a tiered decision-making process, and relying on a volunteer network to enhance monitoring capabilities on HABs of Alexandrium and Pseudo-nitzschia.  Coupled to remote sensing to allow for better detecting, tracking, and study of HAB events.

Dynamics and Mechanisms of HAB Dinoflagellate Mortality by Algicidal Bacteria: 2003-2006; to test the use of algae-killing bacteria to control the red-tide forming dinoflagellate Lingulodinium polyedrum.

The Role of Trace Metals in Regulating Domoic Acid Production and Release by Toxigenic Diatoms. ;2001-2004; to investigate the role of the availability of iron and copper in the water in inducing production of domoic acid by Pseudo-nitzschia.

Regulation of P. australis by C, N, Si Interactions; 1999-2003; to examine the factors causing Pseudo-nitzschia blooms and toxin production.

Domoic Acid in a Coastal Food Web; 1999-2002; to determine the effect of Pseudo-nitzschia blooms on the viability, fecundity, and recruitment of key fish species in the marine environment to provide insight into the relationships between HABs and the productivity of marine fish populations.

A New Chemosenser for Domoic Acid Based on Molecular Imprinting; 1999-2001; to develop a new method for detection toxin in water.
